IMPROVEMENT IN METALLIC SIGN-LETTERS.

Specification forming part of Letters Patent No. [90,695, dated May 15,1877; application filed February J5, 1876.

To all whom it may concern Be it known that I, CHRISTIAN TEMME, of St.Louis, St. Louis county, State of Missouri, have invented a certainImproved Metallic Sign-Letter, of which the following is aspecification:

In this invention the letters composing the sign are cast in separatepieces, and are hollowed out at the back, so that the letters are formedof a thin shell of metal, composed of a front plate and two side and topplates, with an open back. The side and top plates are inclined outward,so as to shed rain, 8tc. Screw-bolts for holding the letters onto asuitable frame or backing are cast onto the front plate of the letters,so that the elasticity of the letters will tend to hold them firmlyagainst the backing frame and prevent the entrance of water into thecavity of the letter, and thereby prevent rusting of the letters.

Figure 1 is an elevation of the back of one letter. Fig. 2 is ahorizontal section at line as :v.

A is the letter, cast hollow with a front plate, a, and top, bottom, andside plates on.

The side, top, and bottom plates are inclined, as shown, so as to shedrain, 850., from the letters, so as to prevent rusting of the same, andalso to give or allow of a slight spring in the letter, so that when theletter is being secured in place the edges of the top, side, and bottomplates at will tend to form a perfect joint with the backing B, to whichit is secured by screw-bolts U; and to more efi'ectually accomplish thispurpose the bolts 0 project from the center of the plate a of theletter, so that the slight spring in said plate may be utilized inaccomplishing the purpose above stated, and also to prevent theliability of breakage in firmly securing the letters in place.

I claim- The sign-letter, having front plate a and inclined side, top,and bottom plates (1/, in combination with the bolts 0, arranged asdescribed, and for the purpose set forth.

CHRISTIAN TEMME.
